[Discuss-gnuradio] error with scopesink.py

when I run ./scopesink.py or ./scopesink2.py, it shows the secret data on an oscope and also gives the following error:

** (python:3390): WARNING **: IPP request failed with status 1030

** (python:3390): WARNING **: IPP request failed with status 1030

does any body know why this error is coming? I also want to know if there is another python file in the gnuradio that can serve the purpose of oscope. I want to use it to visualize signals at various stages of a flow graph.Teka
